Shuffling Based Side-Channel Countermeasure for Energy Harvester
Yusuke Nozaki, Masaya Yoshikawa · 2018
Energy harvesting technology has attracted attention to support internet of things (IoT) system. Also, in the viewpoint of security, encryption of energy harvesters used in IoT system is required. On the other hand, in recent years, side-channel analysis (SCA) revealing the secret key stored in energy harvesters has been proposed. To secure the IoT system in the future, countermeasures against SCA for energy harvesters are very important; however, they have not been studied. Therefore, this study proposes a new shuffling based countermeasure against SCA for energy harvesters. Experiments using an actual energy harvester show the validity of the proposed method.
